Someone else can chime in if I'm wrong but I think you can shoot .44 Russian in that baby as well.

It may appear so at first glance, but unfortunately you can't after checking up in "Cartridges of the World"

The 44 Colt uses a heeled type bullet with a diameter of .443" vs the 44 Russians .429" bullet. You'd be lucky to hit the ground with such an undersized bullet. The rim diameter of the Rusian is larger as well and also has a thicker rim; 0.045"-0.047" for the 44 Colt vs .060" for the Russian.
